I think the 35-70/3.5-4.5 Zuiko would be about perfect for this application,
as it focuses pretty close, although I don't understand why you need to
focus close to use this device...?

I'm not sure why you would need to focus on the mirror (surface) and not on
the virtual image in the mirror... Seems like if you take a 'self-portrait'
in a flat mirror and check the focus distance it will be (approximately)
twice the distance you are actually standing from the mirror. You are
focusing on the 'virtual you' behind the mirror, a distance equal to the
real distance you are in front of the mirror.

Seems like the Kaidan curved conical mirror should work the same way... am I
missing some physic/optics factor here? This does look interesting, I've
viewed some of Skip William's VR panos and hope someday to get my fisheyes
working so I can do it too.
